Abstract: A flexible display apparatus including a substrate including a flat surface portion and at least one curved surface portion, and a display including a first display region above the flat surface portion and a second display region above the at least one curved surface portion. The second display region includes a correcting layer including a first point and a second point apart from each other. The second point is farther away from the first display region than the first point. A thickness of the correcting layer at the second point is greater than a thickness of the correcting layer at the first point. The correcting layer includes a curved portion between the first point and the second point.
